681. Gluphisia severa Hy. Edw. — Banff, May 26th to June 

 1st, 1910. Several specimens on electric light poles (Sanson). In 

 the Kootenai List Dr. Dyar treats severa as a western race of 

 lintneri. Lintneri occurs at Calgary, but is rare. I have eight 

 specimens at present under examination, two of them females. 

 Of severa I have three males from Kaslo, one from Duncans, V. I., 

 and two and a female from Banff. I have little doubt that they 

 are distinct species. In lintneri the coloured shades are ochreous. 

 In severa they are pale sienna brown. But the colour seems vari- 

 able both in shade and degree, and may not always serve to dis- 

 tinguish them. The lines differ in course. A basal transverse line 

 is occasionally present in both. There is also an extra-basal line, 

 about midway between the base and the t. a. In lintneri this is 

 sharply outcurved in the submedian interspace.. In severa it is 

 slightly waved throughout. The t. a. varies in course in both 

 species, but is directed more obliquely outwards from the costa 

 to the subcostal vein in severa. The t. p. line is also more dentate 

 and crenulate in the latter, especially near the inner margin. 

 Structurally, severa is rather broader winged, and the scaling and 

 vestiture is rather rougher. In my female severa, the antennal 

 pectinations are considerably shorter than in lintneri, and lie 

 closer along the shaft, giving at first the impression of a simple 

 antenna. 



LIPARID.4i. 



682. Olene plagiata Walk.— Banff, Aug. 2nd (Fletcher). 

 The record is taken from Barnes and McDunnough's Contr. II, 

 No. 2, p. 75, on "The Liparid Genus Olene." In that work they 

 point that though plagiata Walk, has been quite erroneously used 

 for one species of Olene (vide also Can. Ent. XLV, 301, Sept. 1913, 

 No. 447, of this list), through Acyphas plagiata Walk, iv, 799, 

 1855, having been misidentified, yet the name must immediately 

 be reintroduced for another Olene, which is Edema ^/agm/a Walk. 

 xxxii, 427, 1865, and which stands wrongly in our lists as Sym- 

 merista. I should judge from their figures that this is very likely 

 the species referred to by me from Banff as styx B. & McD., though 

 paler than Vancouver Island specimens (43rd Rept. Ent. Soc. for 

 1912, 121 (1913). Of this Mr. Sanson took four males, July 21st- 

 25th, 1911. As Messrs. Barnes and McDunnough suggest them-
